3 Claims.

This invention relates to barbed wires and method of making the same.

Among the objects of my invention are the provision of an improvedbarbed wire and an improved method of constructing barbed wire in whichthe barbs are arranged in different angular planes and in which suchdiflerent angular arrangement of barbs is produced by twisting sectionsof the barbcarrying wire or strand in opposite directions so that thebarbed wire or strand as a whole will have no tendency to twist and coilas it is wound on the reel or is unreeled and after it has been laid orstrung in position.

Other objects of the invention appear from the following descriptiontaken in connection with the drawing, in which Fig. i is a plan view ofa mesh constructed of longitudinally extending strand wires andtransversely extended barbing wires with some of the barbing wires cutto provide barbs;

Fig. 2 is a side view of a strand and a barb;

Fig. 3 is a view on the line 3-3 of Fig. 2;

Fig. 4 is a view disclosing steps of twisting the strand; and v Fig. 5is a view taken on the line 55 of Fig. 4.

Thmbarbed wire may be produced by welding the barbing wire III asindicated in Fig. 1 to strands II in right angular relation as disclosedin Fig. 1, or in any other angular relationas desired. The diameters ofthe barbing wire and strands may be the same or different as founddesirable. After the mesh has been produced the barbing wire may be outbetween the strands as indicated at I3 to produce barbs as indicated atIl iii all of the figures. Preferably the barbing wire is shearedobliquely at a suitable angle to produce sharp prods I5.

To make the barbed wire more effective, the barbed wire or strand may betwisted by any suitable means, such as hand tools It disclosed in Fig.4, such means being suitable where the strand is of a small gauge and inthis case the twisting may be effected by the user at the place wherethe barbed wire is installed. The ends of a length of the barbed wiremay be seized by the clamping devices l6 and as disclosed in the lefthalf of Fig. 4 a length of wire carrying four barbs is twisted asindicated by the arrows until the barbs assume the relation disclosed inFig. 5

as indicated by Ila, llb, llc, and lld. The adjacent section of thebarbed wire to the right and of equal length is then twisted in theopposite direction as indicated by the arrow at the right end of thefigure until the barbs assume The tools It are preferably placed to gripthe strand adjacent to the barbs as indicated in Fig. 4, the tool at theleft of the figure being at the right side of the first barb on thestrand and the tool in the middle of the figure at the right side of thelast barb oi the first series or barbs. In this way when the section ofthe strand is twisted as indicated by the arrows the barb Ila will bemoved into the same angular relation with respect to the first barb asthat of the barb Ilb with respect to the barb Ila etc. By gripping thesecond section or the strand at the points indicated and rotating thetool It at the right of the figure in the direction of the arrow thefirst barb oi the second series will be twisted angularly with respectto the last barb Ild of the first series and into the plane of the barbllc. In this way all adjacent barbs will be angularly related and theamount of twist of the sections of strands between the barbs will be thesame. The angular relation of the adjacent barbs of adjacent series maybe made exactly the'same as that of adjacent barbs oi the series bygripping the strand at the barbs instead of adjacent thereto.

In cases where the adjacent barbs 0! adjacent series maybe in the sameplane, the center portions of the sections between the barbs may begripped, and, if desired, by three tools and the center tool rotated.

It is obvious, of course, that ii a different arrangement of the barbsis desired that lengths of the barbed wire supporting a smaller orlarger number of barbs may be seized and twisted. If

. it is desired to arrange the barbs in the position disclosed in Ilaand Ilb, Fig. 5 then a length carrying but two barbs would be twisted.If it were desired to arrange the barbs as disclosed at Ila, Ilb andIlc, then a section of the wire carrying three barbs would be twisted.The barb Ila, Fig. 5 is the first twisted barb on the left in Fig. 4.The first barb on the second length will be in the same angular positionas barb Ilc and on the same side of the strand.

The strands may be twisted at the factory as in the case in which thestrands are of heavy gauge and the strands and barbs may becasehardened.

While I have disclosed one form of barbed wire produced by the methodspecifically described, it is to be understood that I reserve the rightto all such-changes in the barbed wire and the method of making the sameas fall within 'the principles of my invention and the scope of theappended claims.

I claim: 7

l. The method of producing a barbed wire with its barbs arranged inangularly related planes from a barbed wire having its barbs arranged inthe same plane. which consists in,twisting the ends 01' a section of thebarbed wire carrying a series 01' barbs relatively in oppositedirections and in twisting the corresponding ends oi an adjacent similarsection relatively in opposite directions with respect to each other andwith respect to the direction 01' twisting of the corresponding ends ofsaid first section.

2.- The method of producing a barbed wire with its barbs arranged inangular-1y related planes from a barbed wire having its barbs arrangedin the same plane. which consists in seizing a section of the wirecarrying a series of barbs. at points adjacent to and on the same sideof an end barb or the series and the barb outside of the series and nextto the other end barb or the series and in twisting said section in onedirection, and in similarly seizing an adjacent section of the wirecarrying a series of an equal number or barbs RAYMOND J.
